you should check includes from pspsdk they are well documented
this is from psppower.h
| Code: |
/**
* Set CPU Frequency
* @param cpufreq - new CPU frequency, valid values are 1 - 333
*/
int scePowerSetCpuClockFrequency(int cpufreq);
/**
* Set Bus Frequency
* @param busfreq - new BUS frequency, valid values are 1 - 167
*/
int scePowerSetBusClockFrequency(int busfreq);
/**
* Set Clock Frequencies
*
* NOTE: Please use scePowerSetBusClockFrequency and
* scePowerSetCpuClockFrequency instead of this function
* for clock <= 222 and bus <= 111.
*
* @param cpufreq - cpu frequency, valid from 1-333
* @param ramfreq - ram frequency, valid from 1-333
* @param busfreq - bus frequency, valid from 1-166
*/
int scePowerSetClockFrequency(int cpufreq, int ramfreq, int busfreq); |
